  1. dinosaur

    A dinosaur is a diverse group of reptiles of the clade Dinosauria that first appeared during the Mesozoic Era, between 230 and 65 million years ago. These creatures are characterized by their upright stance, with legs located beneath the body. Dinosaurs can be either carnivorous or herbivorous, and vary greatly in size, from tiny to gigantic. They became extinct for reasons yet not completely understood, possibly due to a major meteor impact or drastic climatic changes. The birds are the only surviving dinosaurs.

  1. Dinosaur

    Dinosaurs are a diverse group of animals of the clade Dinosauria. They first appeared during the Triassic period, approximately 230 million years ago, and were the dominant terrestrial vertebrates for 135 million years, from the beginning of the Jurassic until the end of the Cretaceous, when the Cretaceous–Paleogene extinction event led to the extinction of most dinosaur groups at the close of the Mesozoic Era. The fossil record indicates that birds evolved from theropod dinosaurs during the Jurassic Period and, consequently, they are considered a subgroup of dinosaurs by many paleontologists. Some birds survived the extinction event that occurred 66 million years ago, and their descendants continue the dinosaur lineage to the present day. Dinosaurs are a varied group of animals from taxonomic, morphological and ecological standpoints. Birds, at over 9,000 living species, are the most diverse group of vertebrates besides perciform fish. Using fossil evidence, paleontologists have identified over 500 distinct genera and more than 1,000 different species of non-avian dinosaurs. Dinosaurs are represented on every continent by both extant species and fossil remains. Some are herbivorous, others carnivorous. While dinosaurs were ancestrally bipedal, many extinct groups included quadrupedal species, and some were able to shift between these stances. Elaborate display structures such as horns or crests are common to all dinosaur groups, and some extinct groups developed skeletal modifications such as bony armor and spines. Evidence suggests that egg laying and nest building are additional traits shared by all dinosaurs. While modern birds are generally small due to the constraints of flight, many prehistoric dinosaurs were large-bodied—the largest sauropod dinosaurs may have achieved lengths of 58 meters and heights of 9.25 meters. Still, the idea that non-avian dinosaurs were uniformly gigantic is a misconception based on preservation bias, as large, sturdy bones are more likely to last until they are fossilized. Many dinosaurs were quite small: Xixianykus, for example, was only about 50 cm long.

  1. dinosaur

    1. Any hardware requiring raised flooring and special power. Used especially of old minis and mainframes, in contrast with newer microprocessor-based machines.

IBM was not amused. Compare big iron; see also mainframe. 2. [IBM] A very conservative user; a zipperhead.

Examples of dinosaur in a Sentence

  1. Harvard University:

    This discovery overturns decades-old ideas that non-bird dinosaurs were restricted to terrestrial environments, so, yes, we believe that this discovery does indeed revolutionize our understanding of dinosaur biology.

  2. Lida Xing:

    We found the dinosaur's huge vertebrae with the skull and the tail, but couldn't find any bones from the hands or the legs. So the locals began to say the long body looked just like a dragon from ancient Chinese stories.

  3. Cindy Howells:

    We know this dinosaur is (was born) 200 million years ago, to within half a million years or so, the rocks down here we've been studying for quite a long time now and we can do direct comparisons with the ages of rocks in Austria, which is where the transition between the Triassic and the Jurassic boundaries is precisely located.

  4. Andrew Farke:

    One of the Holy Grails of dinosaur paleontology is trying to distinguish male and female dinosaurs, i think this is one of those cases that's quite suggestive. I wouldn't say it's necessarily airtight, but it's fairly suggestive of something going with these animals.

  5. Mike Romano:

    The east coast of Yorkshire is known as the Dinosaur Coast for very good reasons, although these different types do not necessarily represent the same number of different dinosaurs, they do indicate a diverse ecosystem of animals including both carnivores and herbivores that roamed the Jurassic coastal plain and (river) complex some 160-175 million years ago. The prints also allow us to interpret their behaviour. Thus, we have records of walking, running and swimming dinosaurs.
